Abstract: The present application discloses a method and eNB equipment for supporting seamless handover. The method comprises the following steps of: receiving, by a target eNB, random access information or an RRC connection reconfiguration completion message from a UE; transmitting, by the target eNB, a data transmission stopping indication message to a source eNB; and, stopping, by the source eNB, transmitting downlink data to the UE, and/or stopping, by the source eNB, receiving uplink data from the UE. The present invention further provides several other methods and eNB equipments for supporting seamless handover. By the methods for supporting seamless handover provided by the present invention, the delay of data transmission and the unnecessary data transmission or unnecessary data monitoring of a source eNB can be avoided, the waste of resources and the power consumption can be reduced, and the missing and duplication transmission of data can be avoided.

Abstract: A data transmission method of a User Equipment, UE, in a Long Term Evolution, LTE, compliant mobile communications network, and a corresponding UE. The method comprises detecting reconfiguration of a bearer from a split bearer in which uplink Packet Data Convergence Protocol, PDCP, Protocol Data Units, PDUs, are transmitted to both a Master eNB, MeNB, and to a Secondary eNB, SeNB, to a non-split bearer in which uplink PDCP PDUs are transmitted only to the MeNB. If reconfiguration of a bearer from a split bearer to a non-split bearer in which uplink PDCP PDUs are transmitted to the MeNB is detected, the method further comprises initiating retransmission of PDCP PDUs from the first PDCP PDU for which transmission was attempted via the SeNB and for which there has been no confirmation of successful delivery by a protocol layer below the PDCP layer within the UE. The method further comprises retransmitting only PDCP PDUs for which transmission of the PDU was attempted via the SeNB.

Abstract: A method of a terminal in a wireless communication system is provided. The method includes receiving, from a base station, a message including first information configuring a medium access control (MAC) parameter for the terminal; identifying whether second information is configured in the first information, the second information indicating the terminal to skip an uplink transmission; receiving, from the base station, an uplink grant; and determining whether to skip a generation of a MAC protocol data unit (PDU) for the uplink grant based on the second information. The generation of the MAC PDU is skipped, in case that the uplink grant is addressed to a cell radio network temporary identifier (C-RNTI).
